Must Read:

The left and right hip bones (innominate bones, pelvic bones) are two unpredictably molded bones that frame some portion of the pelvic support – the hard structure that connects the hub skeleton to the lower appendages.


The hip bones anatomy has three fundamental verbalizations:

Sacroiliac joint – explanation with the sacrum.

Pubic symphysis – explanation between the left and right hip bones.

Hip joint – explanation with the head of a femur.

In this article, we will take a gander at the life systems of the hip bones – their structure, hard milestones.

Section of the Hip Bones

The hip bone is included the three sections; the ilium, pubis, and ischium. Before adolescence, the triradiate ligament isolates these parts – and the combination just starts at the age of 15-17.

Together, the ilium, pubis and ischium frame a container formed attachment known as the hip bone socket (strict importance in Latin is ‘vinegar glass’). The leader of the femur expresses with the hip bone socket to shape the hip joint.

We will now take a gander at the individual parts of the hip bone, and their particular hard milestones.


The Ilium

The ilium is the most stretched out and biggest of the three sections of the hip bone and is found superiorly. The body of the ilium frames the predominant piece of the hip bone socket (acetabular rooftop). Instantly over the hip bone socket, the ilium extends to shape the wing (or ala).


The wing of the ilium has two surfaces:

Inward surface – has a sunken shape, which delivers the iliac fossa (site of the source of the iliacus muscle).

The outer surface (gluteal surface) – has a raised shape and gives connections to the gluteal muscles.

The prevalent edge of the wing is thickened, shaping the iliac peak. It reaches out from the foremost prevalent iliac spine (ASIS) to the back predominant iliac spine (PSIS).

On the back part of the ilium there is a space known as the more noteworthy sciatic indent.



The Pubis

The pubis is the most front bit of the hip bone. It comprises a body, unrivaled ramus and second-rate (ramus = branch).

  • Pubic body

found medially, it verbalizes with the inverse pubic body at the pubic symphysis. Its unrivaled perspective is set apart by an adjusted thickening (the pubic peak), which expands along the side as the pubic tubercle.

  • Unrivaled pubic ramus

stretches out along the side from the body to frame some portion of the hip bone socket.


  • Second rate pubic ramus

ventures towards the ischium.

Together, the unrivaled and sub-par rami encase some portion of the obturator foramen – through which the obturator nerve, supply route, and vein go through to achieve the lower appendage.


The Ischium

The ischium frames the posteroinferior part of the hip bone. Much like the pubis, it is made out of a body, a second-rate ramus and unrivaled ramus.

The substandard ischial ramus consolidates with the second rate pubic ramus shaping the ischiopubic ramus, which encases some portion of the obturator foramen. The posteroinferior part of the ischium frames the ischial tuberosities and when sitting, it is these tuberosities on which our body weight falls.

Close to the intersection of the prevalent ramus and body is a posteromedial projection of bone; the ischial spine.


Two imperative tendons join to the ischium:

Sacrospinous tendon – keeps running from the ischial spine to the sacrum, consequently making the more noteworthy sciatic foramen through which bring down appendage neurovasculature (counting the sciatic nerve) rises above.

Sacrotuberous tendon – keeps running from the sacrum to the ischial tuberosity, framing the lesser sciatic foramen.
